To all whom it may concern: I lie it known that I...\D.\.\l l'ltltll, a eitizen of the United States, residing at San Franl eiseo, in the eonnty of San Franeiseo and t I tate of California, have invented eertain I new and aerial Improvements in Adding- .\laehines. of whieh the following is a speeilit-:ition. l My invention relates to apparatus For 1 adding and recording the numbers added and their totals and more especially to that type of apparatus illustrated in my Letters 1 Patent Nos. t'it thltl and 712.7 5, and consists of eertaiii mechanisms, derives and details tor seeuring economy and simplicity of eonstruetioii and eertainty of operation, as fully set forth hereinafter and as illustrated in the aeeompanying drawings, in \Vl|it'l1 Figure .l is a plan view of an adding ma; l l i l l l l l rhino embodying my improvements; Fig.

The mai-hine has a base A supporting the frame containing the working parts, which are inelosed by a easing B. through the front end of which project key levers l supporting keys V which are numbered from O to 9. The lever 2 of a total key U also extends through the. front of the easing, and above the latte are standards 4, 4, supporting a reel 3 for the paper to be printed. There may also be another lever 133 for a repeater key Y.

At the right of the easing is a hand lever W and a zero lever X, and at the left of the rase is a restoring lever C. At the rear of the frame is a series of wheels of the adder o' accumulator I). (Fig; 8). and near the front the series of sectors of the recorder R, Fig. T. in the front of the casing opposite the adder wheels is a slot g, Fig. 8, through whieh can be seen the numbers of the adder separately on a shaft supported between f the side plates of the frame (Fig. 2), and each has at its periphery teeth numbered in (live series being shown) from O to 9, With the adder wheels eoi'iperates series l ig. 23.

eaeli of which has ten teeth or shoulders and rarries a pawl 88 (l igs. t) and 17) that 011- igages the toothed periphery of the adder wheel on the right, when the segment swings in the direetion ot' the arrow, Figs. 9 and 17. The extent of oscillation of Llltll segment determines the extent ()fltlliltlUll of the eooperating adder wheel, and the segments are oseillated in the direction of the arrow hv means of a soleetor F. This leetor eon .siicls of a elli'ved ftiltllt: i-ai" \'ing series of. radially adjustable U shaped pins it, said Hit 'seleetoi: frame sliding on the em; rials H, U

of a frame I) swinging on the h:ilt i! (Fig. 2) and consisting ol' side pieees it, said rm: rods ti, ti and tlths bars 7:, To. Figs. .2, l0 and ll.

Prior to operating the keys, the lrame I occupies its lower position, Figs. 2, 10, and the selector is at the right of the machine with the inner row of pins above a series of hammers 72, Figs. 2, 8 and 17, at the rear ends of the key levers 1, and i parallel to that of the series of pi s.

\Vhcn a key is depressed, its hammer 72 will rise and push in one of the pins, and on the descent of the key lever the selector will move one step to the left, bringing the inner series of pins, including that raised, beneath the segment at the right. The frame E is then swung to the position shown in Fig. 11, the pin which has been set inwardmaking contact with a shoulder of the segment, Fig. 17, and the latter being swung with its adder wheel to an extent depending on the distance before starting, of the pin from the shoulder 89 of the segment, Fig. 17.

"he hammers 72 are so arranged that the hammer nearest the rear is carried by the lever of the key having the highest numher and so on in succession, the hammer nearest the front being carried by the key bearing the cipher. It therefore follows that the depressing of the key numbered 9 will carry the segment to its full extent, while depressing the key bearing a cipher will impart no movement to the segment until the pin at the extreme left, Fig.17, makes contact with the shoulder 89, when the segment and its adder wheel will move one step.

Each segment is connected with one of the printing sectors 100 of the recorder R by a connecting rod 118, said sector swinging on a cross shaft 116 and being moved the same number of steps as the se ent.

An row of pins above the ammers 72 is un er the control of all the numeral keys, and after one key is struck and released and the selector moves inward one step, the

next row of pins is brought above the row of hammers 72 and one of the hammers of this second row may be pushed inward by the o eration of any numeral key, and on its re ease the selector will move inward another step, and so on until keys corre sponding to the number to be added are struck. Then the frame E. with the selector is swung to the osition shown in Fig. 11 and segments an adder wheels correspond ing to the number of keys struck are actuated. by the selector, the selector then sliding back to the right and the frame E then swinging down to its first position. A pin 90, Figs. 2 and 8, projects inward from one of the side frames through an opening in the frame E and carries a rolling sleeve. The roller pin extends across the selector when the latter. is in position at the right of the machine and clear of the adder wheels. As the selector moves step by step inward, each row in which a piuhas been,

i a plane ends of the adjusted pins make .ripheryof sai adder wheel. in part by a elevated is carried beyond the end of the pin 90, so that said selector pins do not contact therewith when the frame E is swung upward. But after the selector has been elevated, and is then carried to the right, and begins to swing down, the inner contact with the pin 90 and are pushed outward, a result which is facilitated by beveling the inner ends of the pins as shown.

As there are five series of numbers on each adder wheel, the latter is turned one fifth of a revolution at each full movement of its selector, but always in the same direction.

The carrying mechanism-While any suitable means-may be employed for moving each adder wheel one step as the wheel next below is moved in excess of nine steps, I prefer the means shown in the drawing, especially in Figs. 10 and 11, and which I Wlll now describe.

The backward rotation of each adder wheel is revented by a pawl 104, hung to a cross s aft 102 supported by a bracket 105 and the side frame at the left, and having an end in engaging the toothed pe .wheel under the action of a spring 113 connected to the tail of the pawl and to a detent 106 hereinafter described.

Upon the shaft 102 are hung curved levers ,101, one adjacent to each adder wheel, with its front end beveled to engage and be elevated by pins k at the si e of the adder wheel, one to each series of digits thereon, there being one of said pins in position to strike the lever 101 as the adder wheel is moved beyond the ninth tooth of each series. To the forward end of each lever 101 is pivoted a hook 103 having a beveled end which rests normally on a fixed cross ro 111 supported by said end in a position above and out of contact with the periphery of the next higher Each lever 101 is actuated motor consisting o a spring 114 and a cam arm 108, to Mich and the detent 100 the spring is connected, said cam arm swinging'on a cross shaft 109 and having a beveled cam edge 110 which may bear on a roller "pin 112 at the side of the lever 1.01 to depress the rear end of the latter. When the said end of the lever 101 is raised, its pin 112 enters a notch in the cam arm, which then retains it in its clevated'position. The near and of the lever 101 is than above the cross rod of the frame E, Fig. 10.

Un t-he lever 101 is a lug 129 which, in

the ositiou shown in Fig. 10, engages a shou der r of the detent 106 hung to a cross bar 75 o the frame E when the latter swings to the position shown in Fig. 11.

So long as the end of a lever 101 is not struck by a pin Z there is no carrying from one udder wheel to another, but when such pin makes contact with the forward end of: a lever 101, it lifts the latter and carries its pin 112 forcibly out of the notch in the cam arni 108 and down until the cam edge 110 bears thereon, but any further movement is limited by the contact of the lug 129 with the shoulder '1' of the detent 106. In this position, the hook 103 is carried forward to such an. extent that its hooked end is just above but out of contact with the peripheryof the adder wheel below. As the frame E reaches the position, Fig. 11, the cross rod 753 makes contact with the detent 106 and suin s the latter forward carrying the shouliler r from above the pin 129, when the cam ed e of the arm 108 bearing on the pin 112 um er the action of the spring 111 will force down the rear end of the lever 101, carrying forward the hook 103 and bringing it into engagementwith a tooth of the adder wheel beneath, turning the latter one step. This action results of course with each wheel Where a pin it: of the next lower wheel has shifted the lever 101 to carry its pin 112 out of the notch of its can! lever. As the frame I) swings back, the cro s bar 75 passes beneath and lifts all the lever-e101 that. have been operated, brings their pins 112 into the notches of the cam levers and restores the parts to the position shown in Fig. 10.

It will be seen that the action of the pins /r: and adjuncts is to set the parts for action in carrying, but that the actual. carrying movements are effected by the spring motors when the detents 106 are shifted after the adder wheels are set by the action of the selector.

Zero cle1rim.--To carry the wheels to zero after any one or more have been moved one or more steps, I make use of a device on the frame E which will make successive Contact with the pins Z of the wheels which have been put out of position and this device will then turn all the wheels as the frame swings upward, the same members on the wheels being in alinement and the segments being stationary. Thus-the frame E carries a shaft 94 rocking in bearings of the frame with fingers 98 extending between the adder wheels in position (after the shaft 94 is rocked in the direction of its arrow, Fi 11) Vhen' to make contact with the pins 7:. therefore after thus setting the shaft 94 and ins the frame E is swung upward, the toppins of all the wheels-that are moved one or more steps will be met by said fingers and the pins in (and consequently corresponding figures on the wheels) will be brought into line. As shown in dotted lines f, Fig. 1.1, the first of the fingers 98 is set linovenients of the frame .nr advance of the othersso that it will strike the pin in of the first wheel and turn the latter one step ahead of the utllol's. Aslhc lingers bring all the 9's of the wheels into alincnient the added extent of movement so cured by the forward position of the first finger carries the coat-ting first wheel one step forward and the cipher of that wheel i alined with the row of fls of the other whet-ls. As this movement; of the first wheel takes place it carries one to the next wheel (already turned 9 stens) by the devices already described, and the second wheel turns to zero it adds one step to the third wheel and so 011.211] the wheels in sue-ecssion being {turned back one step and the zeros thus are brought into line.

The totalizing shaft 94 is set by the zero lever X on. a shaft rocking in the right side piece of the main frame, and as the frame i) which carries the shaft 94, moves in respect to the main frame, it. is necessary to provide transfer means between the shaft and zero lever permitting such movement. This means may be of different cluirarters; as shown the shaft 94; carries at the outer end an arm 93, Figs. 8, 10 and 11, which when the parts are in the position shown in Fig. 8. ends over an arm 92 carried by the shaft 410 of the lever X, so that when the latter is swung in the direction of its arrow, ii 8, the arm J3 will be rai; and the shaft 94 rocked. A spring 5, 11g. 2, tends to rock the shaft 9-1 in a direction to kee the arm 93 in contact with the arm 92, an as the bearing of the arm. on the arm 99 is near the center of rotation of the frame E, the shaft 94 is prevented from rocking to carry its fingers out of position until they have contacted properly with all the pins Zr. As the frame E approaches the position shown in Fig. 1.1, the arm 93 passes from contact with the arm 02 and bears on a pin 7, and is held in a osition to slide over the arm 92 when the mine I rocks back.

Correcting device.-After striking a key or keys and an error is found before recording, correction may be made by pushing out the pins that have been set inward. As the selector moves under the adder when a pin is pushed in, th -restoring device must move between the adder wheels and the selector, and 1 llltt'O'fOl'L hang abail T, Figs. 15 and. 16, to the shaft (Z having a thin cross blade 8 with a bevel edge, which, as the bail swings in the direction of the arrow, Fig. 15, meets the beveled ends of the pins and pushes them out. The bail may be swung from the restoring lever C in different ways. As shown; the shaft of said lever extends through the frame and carries an arm 9 to which is pivoted a curved and slotted link 10, into the slot of which projects a pin 11 from the side of the bail. In the ordinary E, the pin 11 traverses the slot in the link, but when the .is swung between the restoring lever C is shifted, it carries the bail with it over and depresses the pins. Sec dotted lines, Fig. 15.

The rc%-omZm'.- .\s shown the recorder is a printer in which the series, of printing type carriers of any suitable character, which as shown are sectors 100, move each with the segment to which it is connected. It will be evident that as each segment moves the number of steps corresponding to thenumher on the key depressed, the annexed rccording type carrier will be moved to a like extent, as will also each adder wheel, but the latter will always rotate in one direction while the sectors oscillate.

\Vith the type carriers, Figs. 9 and 24, is combined a platen and feed roll n, Figs. 7 and 9, on a shaft. carrying a knob 306, Figs. 1 and 13, at one end, by which to turn it to feed the paper strip between the roll a and pressure bands 19 carried by suitable guide rolls, all supported on a frame S swinging on a cross shaft 131.

To secure a quick sharp blow of the platen against the type, it is carried forward by a. spring 126 connected to the frame S and the latter is retracted by rotating cams 42 on a shaft 4-1, said cams bearing on the lower ends of the side bars of the frame S with shoulders which pass suddenly from the frame, and with faces 8 which thereafter make contact with the frame and cause the platen to be carried. back against the force of the spring.

The paper is moved at each back movement of the frame S by a pawl 212 pivoted at its lower end to the main frame and en gaging a ratchet wheel 20 on the shaft of the platen. a pawl 21 carried by the frame S also engaging the ratchet wheel and preventing back rotation. A spring 22 bears on the pawl 212.

Total iad'ic'ezfor.-A ftcr a column of numbers has been recorded, the total is printed, and to enable the total to be distinguished from the other, numbers of the column, I

-.{prdvide*'a"liiiebar Q, Figs. 3, 7, and 19,

which, whenever a total is to be printed type carriers and the platen, and preferably by the action of the Aibtal key. As shown, this bar is a, part of o wire bail 225. supported by a swin in frame 200 operated as hereinafter dcscri e so that the line is printed above the total.

The ribbon support and feeds-While any suitable impression means may be used, I show a ribbon a, Figs. 3, 9, 24 and 25, carried by two spools upon inclined spindles 25 and each inclosed by a circular casing 26 slit at one side for the passage of the ribbon from one spool to the other. The spool spindles rotate in brackets of the frame and eachhas at the iower'end a ratchet wheel 27 with which may en age a. spur 80 of a swinging pawl 29 pivoted to the aidjacent bracket, the teeth of the ratchets being reversed and means being employed to throw out one pawl as the other is thrown into engagement with its wheel. Spring pawls 28 secured to the brackets prevent back rotation when the pawls are in action. Each pawl 29 is recessed at the" lower end to receive the shaft 23 which has collars 227 on the outer sides of the pawl-s 29. By movingthe shaft 23 longitudinally, the pawls can be swung away from one ratchet wheel, the other pawls being carried into on agement with the other wheel. To permit the proper lateral play of the pawls, their lower ends are extended between the collars 227, and disks 231. free on the shaft 23, which are pressed toward the collar by an intermediate spring 32. As the frame S swin s forward the operative pawl engages an turns its wheel.

The shaft 23 is set by hand and has two grooves 7) p, Fig. 25, near each end, and passes through an opening larger than the shaft in the side piece of the frame S, and when in either position it is held with the edge of the opening in the groove by the pressure of the spring 22, Fig. 9. The sides of the grooves p are beveled so that the shaft can be readily pushed longitudinally to change its position and reverse the directions of feed.

The, totalizing means-In order to take the total it is necessary to swing each type carrier a number of steps corresponding to the number of steps imparted to the associated wheel 6 during the preceding adding. As the type carriers are all swung to zero after each record, and as in taking the total the number keys and selector do not operate to move the segments, other means are required to effect the movement of each segment equal to the number of steps that have been imparted to the associated number wheel. This movement of the segments is effected by turning all of the adding wheels a complete movement (that is, one-fifth of a rotation) bringing the r )ins k into contact with parts on the s gments. As in adding each of these pins has been carried forward a nwaber of steps equal to the number of: steps imparted ,to the adder wheel, each pin will have dvanced a cor responding number of step toward the contacting part of the segment, and on strikin the latter, the segment andthe connects sector will be movedto a corresponding extent. Of course, this movement of the ins 7: from the position in which they have en set in turning the adder wheels in adding mi ht be effected by d-ifl'erent means, but the ad er wheels themselves are turned togather one-fifth of a revolution as a means of turning the segments from the wheels.

As shown, each segment is provided with a contacting device with which the pins of
